Title: Improvements in or relating to high voltage direct current power supplies
IPC: H02M3/33
Filed: 1951-10-25
Abstract: 707,774. Rectifying. GENERAL ELECTRIC CO., Ltd., and FREEMAN, J. W. H Aug. 22, 1952 [Oct. 25, 1951], No. 25006/51. Class 38(2) A high voltage direct current power supply of the " flyback " type has an oscillatory voltage derived from the output of the circuit which voltage is applied to the input of the circuit so that current flows in the circuit for a time shorter than it would normally do so. A voltage is derived from the coil 6 which is inductively coupled to a choke 1 in the anode circuit of a generating valve 2, the voltage being rectified by a valve 7 and applied to a circuit having a resistor 8 and capacitor 9, this circuit having a time constant which is short compared with the period of the saw-tooth oscillation generated by a valve 3 and applied to the input of the valve 2. The waveforms of the two voltages applied to the input of the valve 2 are such that, together with the bias on the grid of this valve, current will flow in the valve 2 for a shorter interval during each cycle of the saw-tooth oscillation than would have been the case if the sawtooth oscillation alone was applied to the control grid of the valve.

Patent GB-285467-A (GB)
Title: Improvements in radioactive material
IPC: G21G4/06
Filed: 1927-09-22
Abstract: 285,467. Fischer, A. Feb. 19, 1927, [Convention date]. Addition to 278,347. Radiations, treating diseases with.-In a modification of the method described in the parent Specification, loss of the radio-active material when incorporating it with the metal carrier is avoided by making the carrier hollow and inserting the radio-active material therein. The open end of the carrier is then closed by sealing or filled up with a metal plug and hermetically closed. The container is then strongly heated to a temperature below that of the melting point of the metal. Noble metals, such as platinum, are usually employed, preferably in the form of small tubes into which the radio-active material is directly charged or introduced in solution, the solvent being subsequently evaporated. Hermetic closure may be effected by fusing, soldering, screwing to receive a plug &c. Platinum tubes, particularly suitable for dentistry, have internal and external diameters of 0.2 to 0.4 and 0.4 to 0.7 millimetres respectively. In one manner of carrying the invention into effect, finely powdered radio-active material is inserted by a small funnel having a charging opening of from 0.15 to 0.3 millimetres, the inserted substance being compressed to one end by an inserted wire made by spirally twisting a platinum iridium wire, coating it with a high melting platinum solder and drawing it out to the thickness required to fit the tube. The inserted wire is then sealed into the open end of thes mall tube and the end containing the radio-active body heated. To render a tube active throughout its whole length, larger quantities of the radio-active substance are introduced, a wire, constructed as stated above but spirally twisted, is screwed in, thus spreading the substance over the wall of the tube. The 'wire is then fused in position at the open end and the tube heated along its whole length. The section of the inserted wide may be hexagonal, the end filling the open end of the tube being circular in cross section. When the radio-active substance is in solution, insertion is effected by alternately heating and cooling the tube. To distinguish the sealed end, it is flattened or formed with an eye.

Filed: 1926-10-11
Abstract: 275,044. Wiley, R. E., and Mensing, C. E. Oct. 11, 1926. Spreading solids.-Apparatus for the conversion of caustic alkalies into granular form comprises a pot 1 set in a still A, Fig. 1, in which the material is reduced to a fluid condition. The caustic alkali is then conveyed by a pump B and a pipe 2 to a nozzle-head 3, Fig. 2, in the centrifugal distributing bowl 4 which has an outwardly flared top 5. The bowl 4 is locked to a revolving sleeve 8 which is driven by intermeshing pinion 14 and gear 15. The centrifuged alkali is met by a blast of cold dry air from a chamber 20 which surrounds the bowl 4 and is thus sprayed into a chamber C. Surrounding the air-chamber 20 is a collecting hopper 21 the upper portion of which is formed by an annular air passage 22 having ducts 23 leading into the hopper whereby additional cold air-is led into chamber C to carry off the heat withdrawn from the falling granular alkali. On leaving the chamber C by ports 31 the air passes to a cooling apparatus such as coils F, except at the beginning of the process when it contains too much moisture and is therefore discharged. The dried air is returned to the chamber C by leading it into an air-box 26 from which it is led by blower 27 to the air passage 22 or by blower 29 to the air-chamber 20. Dry air is also supplied from a tower T charged with dehydrated material such as calcium chloride. An inert substance such as talc may be introduced in measured quantities through a pipe 37.
